Before describing the present improvements and mode of operation thereof in detail it should be understood that the invention is not limited to the details of construction and arrangement of parts shown in the accompanying drawings,

. which are merely illustrative of the present preferred "embodiments, since the invention is capable of other embodiments, and the phraseology employed is for the purpose of description and not of limitation.

Referring more particularly to the drawings for the present preferred embodiments of the invention and first to Figs. 1 through 3,there is disclosed for the purpose of illustration an antislipping device It! applied to the sole 1 I of a. shoe 12.

As there shown, the device 10 includes a pair of pivotally associated and crossed members l3 and 14; formed by metal strips, which are adapted to be positioned beneath the shoe sole to respectively extend diagonally from one side thereof to the other. Provided at the forward ends i5 and I6 of the crossed members 13 and H are inturned fingers I! and I8 respectively adapted to overlie thewelt portion IQ of the shoe sole, while at the rear ends and 2| of the crossed members I3 and I4 there are preferably provided like inturned fingers 22 and 23 respectively, adapted to overlie the welt of the shoe sole at points spaced rearwardly from the fingers l1 and I8.

Of importance it is to be noted that the crossed members are provided with inwardly extending sections 24 and 25 respectively, located forwardly of the place of crossing 26 and connected by a pivot pin 21 having portions 28 and 29 respectively overlying and underlying the sections 4 and-25 to thus pivotally associate the members I3 and I4.

Likewise, it is to be noted that the cross member 14 atthe place of crossing is formed with a channel shaped section 30 adapted to receive the other cross member M. The provision of this Supplementing the channel section 35 in thus properly maintaining the crossed members I3 an'dl t in association there are preferably formed in the respective members at the place of crossing 26 slots 33 and 32 adapted to slidably receive a pin 33 having a portion 3 1 overlying the upper member I3 and a portion 35 underlying the lower member I4.

Of importance, because of the connection between the crossed members at the pivot pin 27 and also at the place of crossing 26 the strength of the device I9 is materially increased, and this without appreciably increasing the weight of the device. 7

, With this'construction'when the crossed members I3 and M arezpivoted relative to each other to move the gripping fingers I'l, I8, 22 and 23 toward the shoe weld I9 the pin 33 slides in the 7 slots 3Iand 32 and serves to strengthen thedevice and to maintain the members I3 and I 4 in closerelation. v I

Spikes 36 suitably secured to the crossed members and projecting downwardly therefrom provide efficient means for engaging in antislipping relation with the walking surface. Preferably, and as shown, the pins 27 and .33 by which the crossed members I3 and I4 are maintained in proper association, are formed with downwardly projecting portions providing spikes 31 and 38 similar to thespikestfi. a I

For'maintaining the fingers i 1, I8, 22 and 23 in firm gripping engagement with the shoe welt to thus hold the antislipping device ID in proper relation with the shoe there is preferably provided a novel yoke member 39 adapted to be located under the shank or instep portion 58 of the shoe sole and to. grip the shoe welt I 9 at opposite sides thereof. he yoke member may be an integral or nonexpansible element. Preferably, however, and as shown,'this yoke member 39is expansible so as to be readily adjustabl'eto be emciently cooperable with shoes having shank portions of divers widths. It includes a p'airpf slidably and pivotally associated bars 49 and El having respectively at the outer ends 42 and 43 thereof, upstanding flanges M and 45 with hooked'portions 46 and 41 providing fingers '48 and lil adapted to extend over the welt I 9 at'opposite sides of the shoe.

bars 49 and dl of the expansible yoke member there is formed in one of the'bars 9 a longi tudinally extending slot 50 adapted to receive a pin or stud 5I'; having an enlarged head 52, on the other bar 4|. An enlarged head receiving opening53atone end of the slot 59 permits the ready insertion of the stud 5! in the slot. When the stud 5i is subsequently slid in the slot'50 the head 52 overlies the-bar 40 and serves to maintain it in pivotal and slidable relation with the other bar.

In order that the pivotal movement between the bars 40 and AI may be limited to one direction, toward the rear or heel portion (not shown) of 1 the shoe, there is formed at the forward edge 54 of the bar 4| at a point on the opposite side of the stud 5I from the finger 49, an upstanding flange or car 55 adapted to engage with the forward edge 56 of the other bar. Preferably and For thus pivotally and slidably associating the as shown, the forward edge 56 is formed with a plurality of notches 51 therein adapted to receive the stop flange 55 and thus lock the bars from relative longitudinal sliding movement.

In applying the expansible yoke member to a shoe, the bars 49 and II are first pivoted rearwardly about the stud so as to free the stop 55 from the notched edge 56 and then slid relative to each other until the width of the member is slightlyin excess of that of the narrowest part of the shank portion 58. The yoke member is then inserted under the shank 58 of the sole II and the bars 40 and ll pivoted forwardly until the stop 55 engages the notched edge 56. When thus adjusted the yoke member is of a width less than that ofthe forward ball portion 59 of the sole and of the forward portion of the shank 58 so that when pulled forwardly it will wedge opposite sides of the shoe sole and to maintain the stop 55 firmly in the seleced one of the notches 51 there is provided a pair of spring connectors Each of these connectors comprises a coil spring 6| having a link 62 secured to the forward end and fixed as by a rivet 63 to one of the upstanding portions 64 and 65 of the fingers I3 and I4, and having a second link 66 secured to the rear end and fixed, as by a rivet, to one of the upstanding flanges 44 and 4 5 of the yoke member 39.

Concurrently with the pulling of the yoke member 39 into wedging engagementwith the sole, the spring connectors 60 draw the pivotally associated crossed member's'lii and I4 together to cause the ,fingers 'I'L'IS, 22 and 23 to' grip and overlie the shoewelt and" thus securely maintain the antislipping device I9 inassoeiation with the shoe sole.

With this construction it will be readily appreciated that the device I is adapted to be applied to shoes of'divers sizes and that when so applied the spring'connectors 60 will automatically move the gripping fingers I1, I8, 22 and 23 in operative relation with the welt I9. Also, it will be readily appreciated'that because of the manner in which theyoke member '35 is associated'with the shoe that the danger of the same being knocked or :jarredfrom'operative engagement with the shoe sole is minimized.

Instead of the construction disclosed in'Figs. l and 2, the modified antislipping device Ell shown in Figs. 4 and -may be utilized.

' There it is seen that" the'modified device it like the form first described, includes a pair of 'pivotally associated and crossed members !I and andTIZ respectively,adapted togrip and overlie a shoe .welt, andcsimilar inturned fingers i9 and r 85 are. formed on .the rear ends of the members II and-12 adapted to grip-andoverliethe welt I9 at points spacedrearwardly of the fingers ll 'and'I8.

Itis to be noted, however, that in the modified device the pivotal association of the members Hand I2 is not achieved by a pin' connection located forwardly of the place of crossing- 85. Instead,'thejpivotal associationof thememhers II and I2 is achieved solely by a pivot pin 82 having portions 83 and 84 overlying and underlying the members H and 12 respectively; and connecting the same at the place of crossing.- i111 i ii? Preferably and as shown, this pin 82- pas'ses through longitudinally extending slots 85and85 in the members" and 12, similar to the slots 3| and 32 in the form .first described. a As in the form shown in Figs. 1 and 2, one of the=crossed members 12 is formed with a channel shaped section 8! adapted to locate and receive the other member-H. l l

A projecting portion 88 on the pivotpin 82 forms a spike which cooperates with a plurality of other downwardly extending spikes 89 on the crossed members in providing an antislipping means for engaging the walking surface.-

A spring plate 90 extendingbetween' the forward gripping fingers TI and 18, and connected to the upstanding portions 9| and 92 thereof serves to hold the crossed members H and 12 in proper relation and to prevent adverse shifting of the pivot pin 82 in the slots 85 and 86 afterthe de-' vice 70 has been adjusted to fit a shoe :of a'g'iven size. In addition, thespring plate 9ll'servesto equalize transverse forces to which oneofthe cross members might be subjected by distributing the same partially to the other member;

For drawing and maintaining the fingers TI, 18, 19 and 80 in gripping engagement with the welt of the shoe the same advantageous yoke member 39 and resilient connectors 60 disclosed in Figs. 1 through 3 are preferably utilized, the connection between the links 62 at the forward end of the springs BI and the upstanding portions 93 and of the fingers 18 and 80 being suitably achieved by rivets63.

If desired there may beprovided, as shown in Fig. 6, a spring plate 95 suitably secured to the member 12 to overlie the channel shaped'section 81 and thus positively confine the other member ll therein. When such a construction is utilized it is possible to dispense with the pin 82 and .slots 85 and 8E connection disclosed in-Figs. 4and- 5-, the overlying spring plate 95, channelsectionfll and connecting spring plate'90 alone serving to effectively maintain the crossed members in pivotal relation.

Also, if desired the overlying spring plate 95 may be utilized in the formshown 'in Figs. 1 and 2, in which event the pin 33 and slots 3| and 32 connection may be dispensed with with out adversely affecting the firm and secure relationship between the crossed members.

In all of the forms,'therefore,it==is seen that the antislipping device provided by the'present invention is simple in construction, efficient'and readily adaptable for use with'shoes of divers sizes and shapes.

Variations and modifications maybe made within the scope of this invention and portions of the improvements may be'usecl without others.
